    There's still no foolproof way to predict who will develop dementia, but brain scientists say they have identified a new clue: Cluelessness, as in an inability to tell when people are lying or using sarcasm. A preliminary new study conducted at the University of California at San Francisco suggests that the neurodegenerative process responsible for dementia also causes deterioration of regions of the brain responsible for detecting insincere speech. "These patients cannot detect lies," study author Dr. Katherine Rankin, of the university's Memory and Aging Center, said in a written statement. "This fact can help them be diagnosed earlier." It...

    Enlarge Image Lefty or righty? A new study links a larger anterior cingulate cortex (left) to politically liberal views and a larger right amygdala to conservatism. Credit: R. Kanai et al., Current Biology, 21 (26 April 2011) Politics can be a touchy topic, especially when it comes to neuroscience. Researchers who've dared to tackle questions about how people's political leanings might be reflected in the brain have often earned scoffs and scoldings from their colleagues. A provocative new study is likely to be no exception. It claims to find features of brain anatomy that differ between people who identify...
  • Political Views Are Reflected in Brain Structure (Really? I'm shocked.)

    We all know that people at opposite ends of the political spectrum often really can't see eye to eye. Now, a new report published online on April 7th in Current Biology, reveals that those differences in political orientation are tied to differences in the very structures of our brains. Individuals who call themselves liberal tend to have larger anterior cingulate cortexes, while those who call themselves conservative have larger amygdalas. Based on what is known about the functions of those two brain regions, the structural differences are consistent with reports showing a greater ability of liberals to cope with conflicting...
  • Mystery scars on Obama's head - has the President had brain surgery ?

    In pictures, Obama appears to have a long scar which goes up the side of his head and over his crown. Some conspiracy theorists claim they are scars that you would see on someone who has had brain surgery. But without medical records (along with his school records and birth certificate) no one seems to be able to provide an answer as to the cause of the mystery scars. Ben Hart, a blogger for Escape The Tyranny a website which presents itself as a Social Network & Forum For Conservatives, said: 'Obama's almost done with his first term, and we...

    A 2,500-year-old human skull uncovered in England was less of a surprise than what was in it: the brain. The discovery of the yellowish, crinkly, shrunken brain prompted questions about how such a fragile organ could have survived so long and how frequently this strange type of preservation occurs. Except for the brain, all of the skull's soft tissue was gone when the skull was pulled from a muddy Iron Age pit where the University of York was planning to expand its Heslington East campus.

    Even long after it is formed, a memory in rats can be enhanced or erased by increasing or decreasing the activity of a brain enzyme, say researchers supported, in part, by the National Institutes of Health. "Our study is the first to demonstrate that, in the context of a functioning brain in a behaving animal, a single molecule, PKMzeta, is both necessary and sufficient for maintaining long-term memory," explained Todd Sacktor, of the SUNY Downstate Medical Center, New York City, a grantee of the NIH's National Institute of Mental Health.

The study, published online in Human Molecular Genetics, demonstrates that giving brain cells extra parkin genes promotes efficient and...

    The seeds of criminal and anti-social behaviour can be found in children as young as three, scientists have claimed. More researchers believe that violent tendencies have a biological basis and that tests and brain imaging can pick them up in children. They argue that, by predicting which children have the potential to be trouble, treatments could be introduced to keep them on the straight and narrow. If the tests are accurate enough then a form of screening could be introduced in the same way we test for some diseases.

    The human brain is truly awesome.A typical, healthy one houses some 200 billion nerve cells, which are connected to one another via hundreds of trillions of synapses. Each synapse functions like a microprocessor, and tens of thousands of them can connect a single neuron to other nerve cells. In the cerebral cortex alone, there are roughly 125 trillion synapses, which is about how many stars fill 1,500 Milky Way galaxies. This is a visual reconstruction from array-tomography data of synapses in the mouse somatosensory cortex, which is responsive to whisker stimulation.(Credit: Stephen Smith/Stanford) These synapses are, of course, so tiny...

Ever pause and wonder how ostensibly perspicacious individuals can show remarkable errors in judgment? History is filled with people like this, proving repeatedly intelligence is no guarantee of good judgment and decision-making. Why? In the 1980s, American aerodynamicists faced a conundrum: How did the USSR, using comparatively rudimentary computers and without CAD/CAM, nonetheless closely match America's best fighter designs? The answer, not immediately obvious, was that Soviet programmers...

    Israeli scientists believe they have identified why Arabic is particularly hard to learn to read. The University of Haifa team say people use both sides of their brain when they begin reading a language - but when learning Arabic this is wasting effort. The detail of Arabic characters means students should use only the left side of their brain because that side is better at distinguishing detail. (Snip) Both young children and adults call on both hemispheres to help them learn a new task. And using both hemispheres is the right thing to do when reading English or Hebrew -

    THE French have elevated it to an art form, and even the British have got better at it - but chimps can't cook at all. According to one controversial evolutionary theory, early humans developed a taste for cooked food around 2 million years ago, and this set in motion a series of changes that made us utterly different from any other animal. Now the proponents of the cooked-food hypothesis are presenting fresh evidence in support of the idea - and it all comes down to how you chew. The theory, championed by Richard Wrangham at Harvard University, has divided palaeoanthropologists....

    The amount of cholesterol circulating in the bloodstream is partly regulated by the brain, a study in mice suggests. It counters assumptions that levels are solely controlled by what we eat and by cholesterol production in the liver. The US study in Nature Neuroscience found that a hunger hormone in the brain acts as the "remote control" for cholesterol travelling round the body.Too much cholesterol causes hardened fatty arteries, raising the risk of a heart attack. The research carried out by a US team at the University of Cincinnati found that increased levels of the hunger hormone ghrelin in mice...

    Two brain areas fail to connect when children with attention deficit hyperactivity disorder attempt a task that measures attention, according to researchers at the UC Davis Center for Mind and Brain and M.I.N.D. Institute. "This is the first time that we have direct evidence that this connectivity is missing in ADHD," said Ali Mazaheri, postdoctoral researcher at the Center for Mind and Brain. Mazaheri and his colleagues made the discovery by analyzing the brain activity in children with ADHD. The paper appears in the current online issue of the journal Biological Psychiatry. The researchers measured electrical rhythms from the brains...

    COLUMBUS, Ohio – Blocking the function of an enzyme in the brain with a specific kind of vitamin E can prevent nerve cells from dying after a stroke, new research suggests. In a study using mouse brain cells, scientists found that the tocotrienol form of vitamin E, an alternative to the popular drugstore supplement, stopped the enzyme from releasing fatty acids that eventually kill neurons. The Ohio State University researchers have been studying how this form of vitamin E protects the brain in animal and cell models for a decade, and intend to pursue tests of its potential to both...

    SANTA FE — Members of a New Mexico family are suing an Española funeral home after they found their grandmother's brain in the bag of personal effects given to them after her death. The discovery was made the day after the interment, when relatives "smelled a foul odor coming from the bag" they received from DeVargas Funeral Home and Crematory of the Española Valley, according to a lawsuit filed on behalf of four family members in state District Court in Albuquerque. The bag had been left inside a family member's truck overnight. When family members opened it, they found, along...

    Scientists have discovered how to “read” minds by scanning brain activity and reproducing images of what people are seeing — or even remembering. Researchers have been able to convert into crude video footage the brain activity stimulated by what a person is watching or recalling. The breakthrough raises the prospect of significant benefits, such as allowing people who are unable to move or speak to communicate via visualisation of their thoughts; recording people’s dreams; or allowing police to identify criminals by recalling the memories of a witness. However, it could also herald a new Big Brother era, similar to that...

    The NFL is partnering with Boston University brain researchers who have been critical of the league's stance on concussions, The Associated Press learned Sunday. The league now plans to encourage current and former NFL players to agree to donate their brains to the Boston University Center for the Study of Traumatic Encephalopathy, which has said it found links between repeated head trauma and brain damage in boxers, football players and, most recently, a former NHL player. "It's huge that the NFL actively gets behind this research," said Robert Cantu, a doctor who is a co-director of the BU center and...

    NEW YORK (Reuters Health) – Children who don't show normal fear responses to loud, unpleasant sounds at the age of 3 may be more likely to commit crimes as adults, according to a new study. Yu Gao and colleagues in the United States and the United Kingdom compared results from a study of almost 1,800 children born in 1969 and 1970 on the Indian Ocean island of Mauritius to criminal records of group members 20 years later. At age 3, the children were tested to gauge their level of "fear conditioning," or fear of consequences. The idea is that children...
